Hello there, I am a high school student new to physics. I don't quite understand physics as I do Calculus. My main question for physics revolves around is what I can do to understand the questions.
For example, I am learning about the laws of motion. My book introduces the laws and I somewhat understands such as Force = Mass * Acceleration, but as soon as I start the homework, my mind goes blank. For example, one of the questions is A 5.0-g bullet leaves the muzzle of a rifle with a speed of 320m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.82-m-long barrel of the rifle?
When I see that question, I cannot connect acceleration or force to the given data. This situation goes for most questions that I encounter. I can never connect the relations between the data and the things I have to solve. I am wondering how I can connect these data together. I try to understand the formulas also, but I still can't make the connection.
Any suggestions will help a lot for me right now. Thanks.
